In April 2012, quarterly score cards that showed the supply cost for rotator cuff repair, total hip arthroplasty (THA) and total knee arthroplasty (TKA) of 17 orthopedic surgeons were sent to all participating surgeons and their referring primary care doctors. Austin and his colleagues estimated any cost savings that occurred during the 2 year study period and gauged surgeon interest in the score cards as well as score card influence.
During the 2-year study period, supply costs per case in rotator cuff repair and TKA decreased, while supply costs increased in THA. Through the first to the last quarter, Austin noted a cost savings of about $260 for rotator cuff repair and a cost savings of $300 for TKA. However, THA increased approximately $100.
